Espèce Spinoncaea humesi - Planche 1 de figures morphologiquesissued from : R. Böttger-Schnack in Zool. J. Linnean Soc., London, 2003, 137. [p209, Fig.8].
Female (from Red Sea): A, habitus (dorsal); B, idem (lateral left side); C, urosome (dorsal); D, idem (lateral right side); E, P5-bearing somite (setae on left side omitted) and genital double-somite, ventral; F, caudal ramus (dorsal); G, A1; H, P5 (lateral); I, idem (dorsal); J, genital aperture.
Nota: Proportional lengths (%) of urosomites and caudal rami 7.0:43.5:8.7:8.0:17.1:15.7. Relative lengths (%) of segments of A1 measured along posterior non-setigerous margin 7.5:13.4:45.2:12.4:7.5:14.0. Anal somite 1.2 times longer than wide, slightly shorter than caudal rami (measured along iouter margin), or abour as long as caudal rami (measured along inner margin), variation in length to width ratio as shown in table 7. Caudal ramus 2.6 times lionger than wide measured along inner margin and about 3 times longer than wide measured along outer margin; variation indicated in Table 7.

Nota: Proportional lengths (%) of urosomites and caudal rami 6.0:55.7:3.5:3.5:3.5:14.1:13.7. Relative lengths (%) of segments of A1 measured along posterior non-setigerous margin 8.3:18.0:44.9:28.8.
